Investigation of the Effect of Molecular Weight, Density, and Initiator Structure Size on the Repulsive Force between a PNIPAM Polymer Brush and Protein

open access: yesAdvances in Polymer Technology, 2022
This paper focuses on the effect of degree of polymerization (N), density (σ), and pattern size (x) on the interaction force between a periodically patterned Poly(N-isopropylacrylamide) (PNIPAM) brush and protein. The hydrophobic interaction, the Van der

Construction of pendant group functional HTPB and efficient light-harvesting carrier

open access: yesPolymer Testing, 2023
The synthesis, characterization and application of the polymers with functional pendant groups have always been hot topics in the polymer field. A kind of functional polybutadiene (HTPB) derivative containing anthryl and azide groups was synthesized by ...

Patterned polymer brushes

open access: yesChemical Society Reviews, 2012
This critical review summarizes recent developments in the fabrication of patterned polymer brushes. As top-down lithography reaches the length scale of a single macromolecule, the combination with the bottom-up synthesis of polymer brushes by surface-initiated polymerization becomes one main avenue to design new materials for nanotechnology.

Polymer brushes for antibiofouling and lubrication

open access: yesBiosurface and Biotribology, 2017
Surface-initiated atom transfer radical polymerization (SI-ATRP) could provide many merits for the preparation of polymer brush, such as the well-defined chemical configurations, gradient, architecture and thickness.

Linear Rheological Response of a Series of Densely Branched Brush Polymers [PDF]

open access: yes, 2011
We have examined the linear rheological responses of a series of welldefined, dense, regularly branched brush polymers. These narrow molecular weight distribution brush polymers had polynorobornene backbones with degrees of polymerization (DP) of 200 ...
